OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 442,304, dated December9, 1890.

Application filed April 19,1890. Serial No. 348,719. (No model.) i i Toall whom it may concern:

Be it known that I, CHARLES H. BoEcK, of Jackson, in the county ofJackson and State of Michigan, have invented new and useful Improvementsin Oil-Burners; and I do hereby declare the following to be a full,clear, and exact description of said invention, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form appart of this specification.

My improvements relate to that class of oil-burucrs having two or morecircular wicktubes and corresponding circular combustionchambers, theinvention relating chien-y to the construction and arrangement of theburnerconcs and defiectors and to the construction Vof the device forraising and lowering the wicks.

In my drawings I show two wicktubes; but a greater number could -be usedby adding others outside of the two shown, adding thereto relatedmechanism of similar 'form and arranged in like manner.

Figure lis a top or plan View of my im proved burner, the detlectorsbeing broken away to showinterior construction, and a portion only ofthe tank or reservoir being shown. Fig. 2 is a vertical transversesection of the same device on line 2 2 of Fig. l.

The burneris provided with two ci rcular vertically-extending wick-tubesA and l. The tube B is considerably greater in diameter than the tube A,and is placed about the tube Aat a distance from it, the top of the tubeA extending, preferably, slightly above the tube B. These wick-tubesAand B are connected together ucar the bottom by the tubes O O leadingfrom one wick-tube to the other, and a tube D leads from the outerwick-tube B to the oil-reservoir E, from which the supply of oil entersthe wick-tubes. The oil-reservoir lil is located at a little distancefrom the burner and in such relation thereto that the oil is fed bygravity from the reservoir to the wick-tubes through the tube D. Thewiektubes A and B are closed at the bottom, preferably, by bending thelower part of the inner wall of the tube, which walls are constructed ofsheet metal across the bottom of the tube to the opposite wall, and isthen turned downwardly alongside thereof, forming a flange or rim F,which, being placed against the surface ot' the outer wall, is readilysoldered thereto, whereby the wick-tubes are made liquid-tight. Acylindrical tube G, of greater diameter than the outer wick-tube B, is'placed about the wick-tube and enceinpasses it at a little distancetherefrom from near the bottom of the tube to nea-r the top thereof.This tube is secured rigidly to the wick-tube by the sheet-metal bracesll H, located near the bottom of the tube.

The wick-tubes Aand B are each constructed with two longitudinal groovesI I in their inner walls, extending throughout their length, whichgrooves are arranged in the burner in a diametrical line. A smallliquid-tight tube K is located in each one of these grooves and piercesthe bottom of the wicktube and extends from at or a little below thebottom of the wick-tube to above the level of the top of the reservoirE. These tubes are secured liquidtight in the bottom of the wick-tubes,so that no oil can escape through the bottom of the wick-tube about thesmall tubes K K. Small wire shifting rods L L pass movably through thesetubes K K, and at their lower or outer ends are secured rigidly to thecross-head M. A toothed rack N is affixed at one end to the cross-head Mand projects therefrom upwardly into the burner, preferably in theair-passage O within the wicktube A. A i'evoluble rod P, supported inbearings therefor on the bottom of the wick-tubes A and B, is providedwith a pinion I, which meshes with the rack )L This rod is also providedwith a milled head Q, whereby itis conveniently rotated. Similarwick-supporting slides R R are fitted movably in the wick-tubes A andl5, respectively, close about their inner walls, which slides are not aslong as the wick-tubes, but are preferably about two-thirds orthreefourths as long and extend normally from near the top of thewick-tubes downwardly therein.' These slides are each provided near itstop with an annular groove S,i11to which the upper extremities of therods L L, turned laterally to form bearing-studs L L', enter loosely,but with suoli extent of bearing as to carry the IOO slides u pand downwith them as they are raised and lowered'. rIhis constructionV permitsthe slides to be placed within the Wick=tubes and over the studs L L'Without longitudinal adjustment with reference to the studs, as thegroove S, extending entirely around the slide, will receive the studstherein at any part otl its periphery. Thelower ends of the slides R Rare preferably turned outwardly a little, as seen at R' R', whereby aslight flange or bearing is provided, which will prevent the Wick fromslipping oi the lower'end of the slide, about which the wick is pla-cedand to which it is secured, so as to becarried thereon vertically bythe' movementv of' the slide.

As the wick-tubes and the inclosing-cylin der'Gfare of diierentdiameters,- there are. two passages O' and O" besides the passage. O,which extend longitudinally throughl the burner, the passage O being. alcentral one withinithe tube A', the passageO being be-` tween the twoWick-tubesAandlfand the passage O" being aboutA the Ywick-tubef B Withinthe cylinder Gr. rllhe'se passagesia're intended.and-adapted'forthe'passag'.e 0f.l air th erethroughiupwardlyitoaid the:combustion inthechambers atrthetop of the tubes. rl`he passage O' is divided nearitstop,y into. two parts by the short circuiar tiibe.'I`=, somewhat less indiameter thanthe outerwicktube B; whichiis-.located in-the chamber.' atalittle distance therefrom andat adista-nce from theitube A, extendingdownwardly'f'or afdistance froniabout opposite the top offthetnbe B.'lhistubeT is securedrigidly to the. wiektube Eby/the braces I-IH'.Asma-ll-tiil-ie'i'll',` efroon'siderable less. dia-meter than theinterior. ofl thezwick-tube A-,is,-loeated in the top ofy theburner/inthe passage O, andis-secured rigidly tothe wick-tube A bybracesll" H".

The ring proJects in,- Wardly a little distance from the angeV and the aperture in the ring V is somewhat greater in diameter thanthe exterior diameter of the wicketube A. The ring V also projectsoutwardly from the flange V', so that its outer edge-has a diameterabout equaltoV the diameter of the inner Wall of the Wiclztube B, andthis outer edge of the ring V is also turned or curved: on its undersurface upwardly slightly.
